Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

In integrated circuit masterslice technology, it has been the practice to completely tailor the masterslice configuration in accordance with circuit needs. It has now been recognized that it may be, in many instances, more effective to arrange the devices and metallization in a given masterslice configuration, so that a portion of the potential integrated circuit may be prewired in accordance with circuit requirements which are common to all possible circuits in a particular masterslice family, and to then implement the differences between the various masterslices by tailoring only the remainder of the masterslice.

Partially Prewired Integrated Circuit Masterslices

In integrated circuit masterslice technology, it has been the practice to
completely tailor the masterslice configuration in accordance with circuit needs.
It has now been recognized that it may be, in many instances, more effective to
arrange the devices and metallization in a given masterslice configuration, so
that a portion of the potential integrated circuit may be prewired in accordance
with circuit requirements which are common to all possible circuits in a particular
masterslice family, and to then implement the differences between the various
masterslices by tailoring only the remainder of the masterslice.

For example, in many masterslice configurations, the current needed to drive
circuits which are off the integrated circuit chip (driver currents) can range up to
three times the current needed for on-chip connections (internal currents).
Therefore, interconnections between driver circuitry and off-chip output pins must
be of low resistance. Accordingly, the connections between the driver circuit and
the off-chip output points must have extra wide metallization, in order to
accommodate such high-current requirements.

Accordingly, it is proposed that at least one wide metallization path be
provided from each driver circuit to its particular output point. If the driver circuit is
used in the masterslice, its high-current output is already connected to its output
point or pad through a metallization line a...
